I’ve always been used to “.ToolTip” to add a tool tip text to a control. Unfortunately not all Silverlight controls have such a property.
However, Silverlight does provide a class called “ToolTipService” so you can add a Tooltip to almost all Silverlight UI elements.
You can use the class both in the XAML
1: <TextBlock x:Name="txtblkNotification" Text="My Textblock">
3: <ToolTip Content="My tool tip for the TextBlock"></ToolTip>
Or directly in code
1: ToolTipService.SetToolTip(txtblkNotification, "My tool tip for the TextBlock");
I hope someone else finds this useful. (I sure did)
